,IMPROVEMENT l-N COTTON AND HAY'PREssEs.

Specification forming part of Letters Patent No. 24.256, dated May31,1859.

and use my invention, I will proceed to describe its construction andoperation.

A' represents the frame of the press.

IB represents the side of the pressbox, and C the follower.

Dis a plank, which is secured to the lower' side of the follower.

E is a rack, which is`secured to the plank D in an oblique position, asshown in. Fig. 1.

F represents the pinion which actuates the rack E when the machine isinoperation. The pinion F is made of a' spiral shape-that is, the cogs areformed thereon ina spiral orderthe distance of each cog from the centerof said pinion being larger or smaller, respect ively, than thesucceeding Icogs, while at the same time the cogs in the longitudinaldirection advance in a screw-line, thereby giving .the pinion a conicalspiral form. Itis evident that if said pinion-shall be in constant gearwith the rackl?l said rack must havean oblique position, as representedin Fig. 1and also that it must be tapering, as represented in Eig. 2,for as the plank D is guided in its motion by the guides a, and cannotmovesidewise, the teeth on a larger or smaller diameter of the pinioncould not be in contact with the teeth of said rack if the thickness ofthe rack would not increase at the same rate as the diameter of thespiral pinion decreases by its revolution. A'By this simple arrangementI am enabled to impart to the follower C a quick motion at thecommencement of the pressing operation, while as the pressing progressesthe power o f the press is increased, While thel motion of the followerbecomes slower. This is the principle on which all good presses ought tobe constructed, as by it a great deal of time is saved, and I obtainthis object by the simple and effectual contrivance above described.

b represents arack, (shown 'in red,) which may be secured to the lsideof the plank C. The pa-Wls doperate on said rack, and thus prevent thefollower from receding by the expansion of the cotton when the latterhas been subjected to pressure. A

In the operation of the machine the cotton lis filled -into the box B,`and'by turning the crank G the pinion F operates upon the rack E, and asthe pressure increases the Vvelocity of the rack diminishes.

Having thus fully described the nature of myinvention, I would statethat I do not claim the combination of a cogged cam-wheel or gearedeccentric with an inclined rack; but

WhatI do claim, and desire to secure by Letters Patent, is- A l,The-combination of a conical spiral wheel or pinion ,with an inclinedrack, whenthelatter is set oblique to the axisof the pinion,substantially in the manner and for the purpose herein described.
